Dynamics of changes in right-atrial pressure and venous pressure measured in the inferior and superior vena cava at their orifices (central venous pressure) after bolus injection of 20 ml physiological saline or epinephrine (5.0 μg/kg) was studied in acute experiments on cats. The initial pressure in the right atrium was equal to that in caval veins. Pressor stimuli either increased or decreased the right atrial pressure, but always increased blood pressure in the caval veins. Moreover, right… 

Reduction of pulmonary edema after SAH with a pulmonary artery catheter-guided hemodynamic management protocol

It is shown that a significant reduction in the frequency of pulmonary edema after SAH can be attained using a pulmonary artery catheter-guided hemodynamic management protocol.

A Review of Central Venous Pressure and Its Reliability as a Hemodynamic Monitoring Tool in Veterinary Medicine.

A thorough evaluation of the veterinary and human literature is performed to evaluate the role of CVP measurements in assessing volume status in veterinary patients to better understand a patient's intravascular volume status, which would allow early goal-directed therapy.

Establishing normal values of central venous pressure in very low birth weight infants

The normal range of CVP in VLBW infants during the first 4 days of life is wider than previously suggested, and the mean CVP was 4.9 mmHg, which is higher than previous suggested.



A comparison between continuous central venous pressure measurement from right atrium and abdominal vena cava or common iliac vein

In children with no obstruction of blood flow from the abdominal vena cava to the right atrium, the pressure in the abdominal cava or common iliac vein accurately reflects the pressureIn the rightAtrium in accordance with the accepted limits of agreement.

Inferior vena caval pressure reliably predicts right atrial pressure in pediatric cardiac surgical patients

It is concluded that while “central” venous pressures measured in the inferior vena cava and in the right atrium are not statistically identical, any differences are well within clinically important limits.
